Technical Summary This document describes two algorithms, one for source address selection and one for destination address selection. The algorithms specify default behavior for all Internet Protocol version 6 (IPv6) implementations. They do not override choices made by applications or upper-layer protocols, nor do they preclude the development of more advanced mechanisms for address selection. The two algorithms share a common context, including an optional mechanism for allowing administrators to provide policy that can override the default behavior. In dual stack implementations, the destination address selection algorithm can consider both IPv4 and IPv6 addresses - depending on the available source addresses, the algorithm might prefer IPv6 addresses over IPv4 addresses, or vice-versa. Default address selection as defined in this specification applies to all IPv6 nodes, including both hosts and routers. This document obsoletes RFC 3484. Working Group Summary The working group has been working on this replacement to RFC3484 for several years. There has been a very active discussion and there is a strong consensus to move it forward. Document Quality This document has been reviewed by many people and the chairs believe there is agreement in the w.g. to move it forward. Personnel Bob Hinden is the Document Shepherd. Brian Haberman is the Responsible Area Director.
